115 Grk “And they.” Here καί (kai) has been translated as “then” to indicate the continuity with the preceding verse. Greek style often begins sentences or clauses with “and,” but English style does not.
116 The word of the Lord is a technical expression in OT literature, often referring to a divine prophetic utterance (e.g., Gen 15:1, Isa 1:10, Jonah 1:1). In the NT it occurs 15 times: 3 times as ῥῆμα τοῦ κυρίου (rhēma tou kuriou; Luke 22:61, Acts 11:16, 1 Pet 1:25) and 12 times as λόγος τοῦ κυρίου (logos tou kuriou; here and in Acts 8:25; 13:44, 48, 49; 15:35, 36; 19:10, 20; 1 Thess 1:8, 4:15; 2 Thess 3:1). As in the OT, this phrase focuses on the prophetic nature and divine origin of what has been said.
